Classes are underway at Marist College, and there's already a potential outbreak on campus.

Alex Moschos says he trusts his daughter Maria to be safe at school, and that he believes in Marist College's protocols from the day he stepped foot on campus to move her in.

When the Port Washington dad got a call from his daughter saying her freshman dorm was being placed on a temporary lockdown because a student who attended an off-campus party tested positive - he remained optimistic.

"The school has shown that they're doing everything they possibly can. You know, the rest of it is up to the students," he says.

Marist says it tested those students living in the dorm who came in contact with that positive student and their results came negative, so Marist has lifted the temporary lockdown in that dorm less than a day after it started.

Marist says the student who tested positive has not been on campus at all, even for in-person classes.

All of the students who attended the off-campus party were tested, sent home to quarantine and suspended pending a school hearing.
